Photographer's negatives - the most common question I am asked relates to the current location of photographer's negatives - see this post.

Whitehead's picture gallery has been one of the attractions of the Show week. His collection contains high-class specimens of the art both in portraits and landscapes. But his especial forte is one in which few artists excel, that of pictures of interiors of rooms. One of the most effective of these, both in toning and clearness, is that of the interior of the surgery of Mr Merewether, dentist...

Mr H. N. Whitehead announces in another column that he has just started as a photographer in this town, in the premises between the Bank of New Zealand and the Red House, in Main-street. Mr Whitehead's long experience with his brother at Hastings in the Hawke's Bay district, should be a sufficient guarantee that the work executed by him will be of a first-class character, and we are satisfied from specimens seen that he is sure to please his patrons. Mr Whitehead makes a specialty of family groups, and undertakes to take his camera to any part of the district free of charge.

"Alf" by Phil Boswell - Copland Pass in January 1966.
This print was taken during a crossing to Westland from the Hooker Valley. We stopped to put on parkas and crampons before the final slope and this was the first of the morning sunlight. The day was rather overcast with very high cloud. The light was reflected from the snow onto the left side of Alf''s face and this shot was sneaked while Alf was busy with the oranges.
This is one of the first large prints attempted and had to fix this in the baby bath. Had the developer up to temp but by the time the test strips were completed the temp was down to 53° and the development was extended to 3 minutes. Wash water temp down to 36° and print was washed for a full 24 hours in fast flow then given a final rinse in warm water.
